Switching between wifi to data and vice versa

[Torx]

i figured out the issue, but i need a solution to the isssue.

i have my wireless router setup for static clients, my phone, 360, xbox, pc, etc etc
after setting up wifi on the phone with a static ip etc in the connections/wifi/configure network adapter/ieee 802.11 wifi adapter, wifi works and everythings peachy

but once i turn off wifi i get no data connection despite turning the phone off and on, and mucking around with comm manager.

now, i figured out why its not working but i need a solution.

once i went back to configure network adapter/ieee and set it to "server assigned..."
data works again.

so it seems like when i want wifi access i have to manually input the static ip then remove it when i want to go back to data.. wtf!
anyone have a simple solution to this hassle? do i need to turn on dhcp for the phone only or something? i would prefer the phone to have a static ip.
